srncrrr'cnr'rolv forming part of Letters Patent No. 326,092, dated" september 15, 188s.

Application filed June 16, 1885. (No model.)

To all whom, t wtay concern:

Be it known that I, JULrUs BEGTRUP, a subject of the King 'of Denmark, residing at Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Steam-Engine Governors, of which the following is a speciication.

My invention relates to an improved gov ernor for steam-engines, of the class of governors that turn with the crank-shaft and regulate the steam-supply and speed of the engine by changing the position of the eccentric which operates the steam-induction valve; and the object of my improvement is to provide a governoi1 which is quick and certain in its action, and will keep the engine on a uniform speed, whatever the load or steam-pressure may be. These objects I attain by the mechanism illustrated in the accompanying drawings.

Figure 1 is a front elevation of a governor of a well-known type, on the back side of which the mechanism comprising my invention is attached, and which is clearly shown in Fig. 3, bei-ng a back view, and in Fig. 4, which is a section on the line a b, Fig. 3.

Similar letters referto similar parts throughout the several views.

A is a pulley keyed to the engineshaft, on which the governor is mounted. B is the eccentric; G, the governor-weights, sometimes called balls5 D, the springs which resist the centrifugal force of the Weights, and E the connecting-links between weights and eccentric. F are shafts to which the weights are keyed. These shafts extend through the arms .of the pulley A, and have levers G on their other ends. These levers are slotted to receive the bolts H, which are held in position by sleeves I, washers L, and nuts K, as clearly shown in the enlarged sectional view, Fig. 2. On the sleeves I are mounted rollers M, extending through slots N in the two concentric circular disks P. By this arrangement 4 5 the position of the rollers M on the levers G can be adjusted to suit circumstances. Each shaft, and thus free to move in conjunction with the levers G and weights C.

The operation of my improved governor will be as follows, to wit: When the engine is not running, and immediately after it has been started, the Weights C will take the position shown in the drawings; but when the speed of the engine has reached a certain limit the weights tly out, turning the eccentric part of a revolution and causing an earlier cut-off of toward the shaft or away from it, as the case may be. Besides-this unbalanced centrifugal force or spring-tension, the force of inertia of the disks P will, in my improved governor, act' upon the weights C. When a momentary change of speed occurs, the disks P will, on account of their inertia, have a tendency to retain the normal speed, and consequently eX- ert a pressure on the rollers M, and this pressure is transmitted through the levers G and shafts F to the weights C, thus causing a quicker shifting of the eccentric than would be the case when the centrifugal force or spring-tension alone had to do it. Besides, the disks P will, on account of the inertia of their mass, prevent undue oscillating movements of the weights.

Although I, for the class of governors illustrated in Figs. 1, 2, 3, and 4, preferably lwill employ two disks, P, in order to equalize the strains on the levers, my invention will cover the application of one disk, P, in connection with one of the levers G in the class of governors here illustrated, and the application of one disk, P, to a class of governors of a somewhat different but well-known design, an example of which is illustrated in Figs. 5, 6, 7, and 8. Fig. 5 is a front view, and Fig. 6 a horizontal section through center of pulley. My invention is here shown as applied to a IOO governor of the class where the eccentric isv shifted across the engine-shaft. This shifting of the eccentric is in this improved governor effected by the centrifugal force 'of the balls C in conjunction with the inertial force of the disk P, substantially in the same manner as by the class of governors first mentioned,with this exception, that I in this case preferably will make the arm R with a projection, S, cast in one piece with said arm, and having a radial slot to receive the head of the bolt H, as clearly shown n Fig. 6, and in Fig. 7, which is a back view of the eccentric and arm, and Fig. 8, which is a section through ef, Fig. 7. The bolt H carries the sleeve I, Washers L, and roller M, extendingthrough the slot Nin the circular disk I, substantially in the same manner and for the saine purpose as by the governor rst mentioned, and illustrated in Figs. l, 2, 3, and 4.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In an automatic governor, the combination of disks or disk P, mounted on roller-bearings on the engine-shaft, said disks or disk having slots N containing the rollers M, mounted on sleeves I on bolts H, these bolts being adjustable on the levers G, and retained in position by nuts K with the shafts F, having slotted levers G to receive the bolts H, substantially in the manner and for the purpose set forth.

2. In an automatic governorhavingaloosely-journaled disk,P,a slotted projection, S, on the arm R, to receive the head of an adj ustable bolt, I-I, in combination with sleeve I and roller M, substantially in the manner and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
